Ixia (Nasdaq: XXIA) today announced that it is revising its revenue guidance range for the fourth quarter of 2012 and currently expects revenue to be in the range of $123.5 million to $124.5 million, above its previously stated guidance range of $118 million to $122 million. Ixia also indicated that it expects fourth quarter combined revenue from its two recent acquisitions, Anue Systems, Inc. (“Anue”) and BreakingPoint Systems, Inc. (“BreakingPoint”), to be in the range of $30 to $31 million, compared with its previously stated guidance of $26 to $28 million. Both GAAP and non-GAAP diluted earnings per share for the fourth quarter are expected to be at, or slightly above, the high end of the previously given guidance.

“Ixia delivered an impressive fourth quarter with strong momentum across all of our solutions,” commented Vic Alston, Ixia's president and chief executive officer. “The integration of our Anue and BreakingPoint acquisitions is tracking well and we are increasing our presence at enterprise and service provider accounts. Ixia is well positioned to help these customers accelerate and secure the delivery of applications over their mobile and data center networks.”
